Thanks Bozo,
Why did your DIY scrubber not work?
I Ghetto tested stanley blower by sealing thick plastic over door sealed with tape.Cut 6" hole and stuck duct from stanley intake side(suction) and peeled tape and plastic right off the wall.

I am in woodworking stage right now.Everything cut, now to assemble.I figure i'll have to do some experiments to get it perfect.

Pics were great.That's the stuff I'm looking for.

New guy set-up I'm trying to work with what I have allready.I have a 8", 350 cfm exhaust fan from a small greenhouse and one of those little Stanley blowers that manual says 3 speeds 190/260/310 cfm's.Is BEST way to have stanley blowing thru 6" duct(total 8' long)thru cooltube and out.AND to have the exhaust fan pull through a diy square 10" carbon scrubber directly no duct work?I have 120lbs of activated carbon in a tub.Room is 36"long,30" deep and 85" high with 400 watt dual mh/hps.Thanks ahead.
